Be it known that 1 W. RIQKA.BD, of Chicago, in the conntyof" Cook, and State of` lll'inois, have invented a new and improved Machin-eifor Making Pearl-Barley, itc.; and I do hereby 'declare that the following is a full, clear, und exact descriptonthereof, whichwill enable others skilled in the art to makeund use the same, reference being had to the accompanyingdrauings, formingpart of this specification. l j

Figure 1 is a vertical longitudinal section of my improved machine, taken through the line z x, lig. 8. -Figure 2 is a side view of the seme,'partly in section, through the linez, g. 4.

v Figure '3`isa horizontal cross-section of the same, takenthrough theliney y, fig. 1. y Figure 4 is a top'vew of theseme. i l

Similar letters of, reference indicate corresponding parts.

Myinventien has for its object to Vfurnish an ,improved machine for 'making pearlbarley, lpearl-wheat, hnlling buekwheat, splittng p'eas, removing a part of the vlnanfrom wheatbefore making it into flour orfarina, and other similar purposes, which willrdo its Work quickly and well, and which will not be liablel to get out ot' order; and it consists in the construction, eourbinatiomand arrangement of the various parts, as hereinafttei` i more fully set forth. l i y t s y his the freine of thev machine. B- isthe 'drivinggshnftqvhich `sverticahand tha/lower end of vwhich revolves in the lower central amiss-baraJ oi"4 the frame A, and the upper partof `:which revolves in bearings in the uppecentral cross-har of saidframe. is the cylinder, the central part ofwh'ich is a wooden cylinder, c, tting upon `the shaft '.B. Upon the cylinder c are placed toothed nd. toothless rings, 'c2 and alternating with each other. "The rings c* shouldfbe inade of steelV or other suitable material, and in their edges-are formed 4straightteeth, similar to the 'te'ethof 'aline circnlarsa'tv, to which teeth a slight set .may .be given. 'illhe teeth upon all the rings orrirc'ular plates c Vshouldnll be of the same shape and size, and the plates should -be so.

arranged upon thecylinder cl that'thesaid teeth may be in line vertically. Thisenahles the teeth to be sharp-V ened v vith a iile without removing the plates from theirploces.' The -rings or plates ci shouldbe vmafie without teeth, land alittle sinallertlian the ringe ab as to'leave a small'space between 'the teeth of the said rings, to enable them to operate properly. v'The -rings c"'i'l ia"lu`` made of: anyv suitable' light material.` The rings or plates c and c are all held in their proper relativepositions by bolts,c, passing'through them and through the end plates ci, which are mede heavier than the others, and which are secured' to the-shaft IB hy set-screws, as

shovvn in ig.1.,v D is the outer' case,;vshich Vis ma'de'of sheet'lo' thin plate iron, surrounds the cyliuderG, and

is securely attached'to `the-frame A. The casing D is'e perforatedwith four 'vertical rowsfof long holes or slots alternating with three or four rows of round holes. The holes Iin ths` case 1 are all punched inward, the lips of two rows of each setoi' long holes' yinclining-to the; rghtfandthelipsl of the other ttm rows inclining tothe left, so that the machine nx'ayfworlr equally wcllvfhenrev'olved .ineither direction. The round holes are similar to the holes in 'an ordinary greter.' is'th'edriving-pulley, which is-secured -to the lower part'of the shaft B below-th bottom of thefcnsing D,as shown in fig.- 1. f, The grain .todae operated yupon 'is' introduced through onefor the otherofl the hoppers' F F?. G' is ai fan-sham'beswhieh is secured to the frameAV above the top of the casing-1),.through'thefcentre-ofy which the upper'.V part ci" the shaft lB-passes, and which is connected with .thc 4space between -the cylinder C end casing" bya `throiitor passageway-Eels shown in iig. 1, the draught through which is regulatedhyan openingiuthe tube that connects the funschambergv'rith the top of the easel),

and which opening Sis-.covered with a sliding rin,g;, so'thc.t` the strength of the draught may be regulated b'y the admission of more or'less airthroughsaid opening. 'JH are'the funs, `which arefsecured to the shafty B, seras to.

vbe operated the revolutionV of said-shaft. The fan-chamber Gis provided'with two dischargefspouts, g1 and g, furvished'with sliding gates g5, so that vone or the other spont may'bew'closed,"according-to thedirection in 'which the cylinder C is revolving.` "I is the dischargefspout, through which the grain passes from 'the machine to `theelevator J, being exposed, u ring itslpa'ssage, to the b'lastrof'air exhausted through the exhaust-pipe K, the

upper end ol' whichterlninates it( the faul-'chamber lGr.4 The elevator J, about ,the construction of which thee'is l nthing new, is represented as-heng'attached to the frame A, 1andas being operated from tlreshaft y'IB by a hand and pulleys, but its position is,V entirely immaterikand `it inybe placed Wherever ymost convenient.` Thegrain is discharged from the elevator J into the screen'pL, the holesof whichshouldbe of Isuch a sizeras t permit tue finished grain to pass through `iutonoiue suitable receptacle, v'while the unfinished grain passes from the screen' toene orthe other of the hoppers, according to ihedirectox'l` in which the cylinder is revolving.

-Inusing' the machine, .ofwhich are closed'. The lmachine is then started; th-e gate of the-proper discharge-pipe, gi or g2, is then opened offair exhausted through the interior of the machiuecarries o the lighter particles of bran, Src., and they are discharged from the fanfciiamberl G'r through lthe*discharge-pipe gor 9?'. As theugrain .passes through the discharge-spout I to rtlle'elevator J, the draught of air exhausted' through the pipe K carries the heavier particles of bran, Sec., 'into the fan-chamber G, from which they a're discharged 'through the spout g1 or g2. As the grain is discharged fron! the elevator J into the screen L, the finished grain falls'throu'gh the screen, while the unuished grain passes from the said screen into `the empty closed hopper, from which it may be again admitted to the machine, the mouth of said screen being provided with a pivoted guide-board, l', so that theunnished grain may be directed into either hopper, as desired. The'screen L may be agitated or shaken by an arm, M, pivoted to the frame A, and operated by a cam formed upon or attached tothe shaftB, .said arm-being held np against said cam by an elastic band, N, or other equivalent-spring.

I claimas new, and desire to' secure by LettersPatent* 1.l The cylinder C, constructed substantially as herein 'shown and described, in combination with the perforated casing- D and shaft B, as and for the purpose set forth.

2. Forming the long holes or slots in the casing D with thei'rlips inclined to the right and to the left, subthegrain to be' operated upon is placed in one of the'hoppers Fl F?, the gates of both l and the grain is admitted to the machine. As the grain ispassing through the machine, the draught j stantially as herein sho-wn and described, so that the machine may work equally. well whether run backward or forward.

1 3. In combination with the cylinder C, case D, and shaft B, as constructed, I claim the fan-chamber Grandl v fan H, as set forth, for ythe purpose specified.
